finebykris Posted October 23, 2008 Share Posted October 23, 2008 Im not sure if both my cores are actually being used. How can I check? Ive noticed that I cant play 1080p movies in quicktime smoothly, even now that im OC'd to 2.56ghz. Im running iDeneb 10.5.5 btw. Link to comment Share on other sites More sharing options...

ulimate Posted October 24, 2008 Share Posted October 24, 2008 perhaps, your graphic card driver is not properly installed so the GPU doesn't provide hardware acceleration. Check it. and I have witnessed some Intel GMA GPUs can't play 1080P (H.264) well no matter how tough the CPU installed in Windows XP. GMA X3100 with Q6600...
